Distal structure of leg for musical instrument stand

Abstract

The distal structure of a leg for a musical instrument stand is constituted of a spike member installed inside the storage of a case having a ground portion whose ground surface is placed on the floor, a rotor interconnected to the spike member, and a single operator projected above the case. Upon a first depression, a presser of the operator depresses a projection of the rotor downward so that the spike member protrudes from the ground surface. In the protruded state of the spike member, the projection of the rotor is engaged with a receptor formed in a stepped interior of the storage. Upon a second depression, the presser of the operator depresses the projection of the rotor again so as to release the engagement between the projection and the receptor, so that the spike member moves to retract inside the storage of the case.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to distal structures of legs for musical instrument stands and in particular to mechanisms for protruding and retracting spike members from lower ends of legs.[0003]The present application claims priority on Japanese Patent Application No. 2009-12796, the content of which is incorporated herein by reference.[0004]2. Description of the Related Art[0005]Musical instrument stands for supporting musical instruments at desired heights, such as stands for supporting drums and cymbals, have been widely used and each constituted of a plurality of legs placed on the ground or floor, a support rod which is vertically elongated and interconnected with the legs, and a holding member which is attached to the upper end of the support rod so as to hold a musical instrument. For example, Patent Documents 1 and 2 disclose stands which are equipped with spike members at distal ends of legs for the purpose of...

AI Technical Summary

Benefits of technology

[0013]It is an object of the present invention to provide a simple distal structure of a leg for a musical instrument stand, allowing a player or user to easily protrude or retract a spike member from the lower end of a leg placed on the floor.

[0017]The above switch allows the spike member to protrude or retract from the ground surface upon simple depression of the operator. The present invention does not need the troublesome operation for repeatedly loosening and tightening bolts used in prior art and makes it possible to perform the protrusion / retraction operation of the spike member and the setting operation of a musical instrument in a short period of time. Since the present invention requires a single operator which can be easily recognized by the user, it is possible for the user to perform the above operations with ease, and it is possible to simplify the distal structure of a leg compared to the conventional structure using multiple buttons.

[0018]In addition, the present invention implements the “simple” switching mechanism including the presser of the operator, the projection of the rotor attached to the spike member, and the receptor aligned in the stepped interior of the storage of the case, allowing the spike member to easily protrude and retract from the ground surface upon simple depression of the “single” operator.

Problems solved by technology

This is a complicated and time-consuming operation for a player or user operating the spike member to protrude or retract from the lower end of the leg, which in turn causes a substantial load for him / her in setting the stand holding a musical instrument at a desired position.

In addition, two buttons lead to a complex structure for protruding and retracting the spike member from the lower end of the leg.
